Sven was going for his morning walk one day when he walked past Ole's house and saw a sign that said, "Boat For Sale." This confused Sven because he knew that Ole didn't own a boat, so he decided to go in and ask Ole about it.
"Hey Ole," said Sven, "I noticed da sign in your yard dat says 'Boat For Sale,' but ya don't even have a boat. All ya have is your old John Deere tractor and combine."
Ole replied "Yup, and they're boat for sale."
